3) Suppose, V DSB-SC as follows: Are the following spectrums correct? The carrier frequencies are given as an example.

Here's my work: Could someone please confirm my answer?

In the function generator, I can change the amplitude, frequency, and the offset, if I use it as sine wave. If I use it as square wave, I can change the duty cycle too. As our instructor said, the 1st stage is comparator, so the result would be a square wave ( Vo1). The 2nd stage is a...

I solved all the parts, can you please check my results? figure 1: Figure 2 & Figure 3: Result of fig2 : Results of Figure 3 (Vo1,Vo2, & Vo, respectively): I am not sure about Vo in figure 3, because the value of the rightmost resistor in figure 3 is not written. I assume it's 1k,. This...

The amplitude and frequency are mentioned in the question. Is this result acceptable or I have to adjust the scales?

Yes, XFG1: sine wave XFG2: square wave I am trying to get a result similar to this:

Here's what I got:

Here's my second attempt: However, the result is not as expected to be.

I was meant to write "cm" not "m" but I can't edit now.

I tried to simulate the circuit shown in fig 1 using Multisim and here's my work: The result: I do not know where is my mistake, could someone help me figuring out the problem? Any help would be greatly appreciated!

Apple pay does the job, but it's preferable to choose a way/application that works for many systems not only the Apple.

It's for a project as well. I found that the length of the gap between the coils of 20m is suitable, but I'm looking for an optimum gap for the coils. So, I am asking if the length is reduced to 10m, for example, would the difference on the efficiency, the losses, .. be too much? Is it worth it ?

It's for a project. Yes, I did a search but did not get the procedure of an automatic bill payment (without the need of scanning a QR code, for example).
